 Key bindings for git objects
 ----------------------------

-I have [blogged](https://junegunn.kr/2016/07/fzf-git) about my fzf+git key
-bindings a few years ago. I'm going to show them here again, because they are
-seriously useful.
+Oftentimes, you want to put the identifiers of various Git object to the
+command-line. For example, it is common to write commands like these:
+
+```sh
+git checkout [SOME_COMMIT_HASH or BRANCH or TAG]
+git diff [SOME_COMMIT_HASH or BRANCH or TAG] [SOME_COMMIT_HASH or BRANCH or TAG]
+```
+
+[fzf-git.sh](https://github.com/junegunn/fzf-git.sh) project defines a set of
+fzf-based key bindings for Git objects. I strongly recommend that you check
+them out because they are seriously useful.

 CHANGELOG
 =========

+0.33.0
+------
+- Added `--scheme=[default|path|history]` option to choose scoring scheme
+    - (Experimental)
+    - We updated the scoring algorithm in 0.32.0, however we have learned that
+      this new scheme (`default`) is not always giving the optimal result
+    - `path`: Additional bonus point is only given the the characters after
+      path separator. You might want to choose this scheme if you have many
+      files with spaces in their paths.
+    - `history`: No additional bonus points are given so that we give more
+      weight to the chronological ordering. This is equivalent to the scoring
+      scheme before 0.32.0. This also sets `--tiebreak=index`.
+- ANSI color sequences with colon delimiters are now supported.
+  ```sh
+  printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
+  printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi
+  ```
+- Support `border-{up,down}` as the synonyms for `border-{top,bottom}` in
+  `--preview-window`
+- Added support for ANSI `strikethrough`
+  ```sh
+  printf "\e[9mdeleted" | fzf --ansi
+  fzf --color fg+:strikethrough
+  ```
+
 0.32.1
